Traveling as an engineer

Hello! I am currently a student at Mizzou, and earning my major in Bioengineering. I'm the type of person where I want to travel and help other countries through engineering. I realize there's Engineers Without Borders but I'm considering a minor like French to not only help me separate myself from competitors but I feel like it can help my dream of traveling as well. I was wondering if it's possible to travel as an engineer and help out?
